A method receiving an input signal at radio circuitry, sampling the input signal, and determining a power level of the sampled input signal. The radio circuitry includes an input switch having an input, a first output, and a second output. The input switch is configured to switch between the first output for the receive mode and the second output for the transmit mode. The method also includes determining whether the power level of the sampled input signal is greater than a threshold power level. When the power level of the sampled input signal is greater than the threshold power level, the method includes switching the input switch to the second output for the transmit mode. When the power level of the sampled input signal is less than or equal to the threshold power level, the method includes switching the input switch to the first output for the receive mode.
